One of the most interesting aspects of the study of change among a people after they have had contact with an alien civilisation is not only how they change but also how much they retain of their traditional ways - continuity in change. This book examines the question as exemplified by the Tolai people of Matupit, a small island near Rabaul. The Tolai of the north-eastern Gazelle Peninsula are among the most sophisticated and wealthy indigenous people of New Guinea and occupy a prominence in the affairs of Papua-New Guinea out of all proportion to their numbers.

Dr Stephen FitzGerald is Professorial Fellow in Modern Chinese History, Head of the Department of Far Eastern History and Head of the Contemporary China Centre in The Australian National University. He was formerly a member of the (then) External Affairs Department from which he resigned to enter academic life. In 1971 he accompanied the then-Leader of the Opposition, E. G. Whitlam, to China and in 1973 he was appointed first Australian ambassador to the People's Republic of China.

Chinese influence, culture and power have always moved southward since the first age of which we have reliable historical evidence. In this book Professor FitzGerald tells the story of this southward expansion, both in the lands most directly affected by it - Yunnan which ended as a province of China, and Vietnam, north and south, which was once within the Empire, but has not been so since the end of the T'ang Dynasty - and in the further countries of Laos, Cambodia, Thailand and Burma, which all to varying degrees came under the influence and acknowledged the power of China.

Landscapes which contain moving water are perhaps the most sccnically attractive, and to a geomorphologist have long been a central focus for landform studies. Humid Landformsexamines from a novel angle the effects of running water on the landscape, emphasising the processes changing valleys and rivers. The author takes the humid tropics as the most characteristic case of landform evolution through water erosion and deposition and treats humid temperate lands, previously accepted as the 'normal' pattern of landform evolution, as a variation of the situation in the humid tropics.

Among the chief reasons for the weakness and ultimate collapse of the imperial system of Han were the social and political divisions which arose between the emperor and the scholar-officials who served him. Portents of Protest, which forms part of a continuing study of the reigns of the Emperors Huan and Ling, the last effective rulers of Han, discusses the criticisms that were made of imperial policies and the philosophical background to the debate.

High in the New Guinea mountains a sociological drama of unique design has been unfolding since the early 1930s. At that time the first of the Europeans who would take part in the area{u2019}s development trekked into the remote highlands. These early gold prospectors, patrol officers, and missionaries made the first outside contacts with the Stone Age Gorokan people. These encounters ultimately catapulted the Gorokans, subsistence gardeners cultivating sweet potatoes and raising pigs, squarely into the twentieth century.

New Guinea today is the largest, if not the most populous, non-self-governing territory outside the Communist world. It includes some of the most recently contacted primitive races known to mankind, and its population comprises hundreds of tribal groups whose native languages are mutually unintelligible.

This is another volume in the series, An Introduction to Systematic Geomorphology. It is concerned with the landscapes produced where water exists commonly in solid form - as ground ice, as snow, or as glacial ice. Although the present distribution of glaciers, snowbanks, and frozen groundwater is relatively limited, these phenomena were much more extensively distributed during the Pleistocene ice ages and they have left their mark on the landscapes of almost all parts of the temperate world.
